PAINT-MIXER.

T 0 all whom it may concern:

Be it known that I, JOSEPH F. TOMLIN- SON, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Paint-Mixers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact'description.

- This invention relates to certain improvements in paint mixers adapted to be placed in and upon a paint pail of suitable dimensions having a bail by which the mixing device may be detachably locked to the rim of the pail during the paint-mixing operation.

The main object is to provide simple means for quickly attaching the paint mixer to the pail and at the same time to allow free operation of the mixing device through the medium of a hand crank.

Another object is to provide for a more thorough agitation and mixing of the paint from the bottom up by gradually elevating the solids at each revolution of the mixer and, at the same time, agitating the raised solids in the oil.

Another object is to provide simple means for changing the speed of rotation of the agitator without varying the speed of the prime mover.

Other objects and uses will be brought out in the following description.

In the drawings Figure 1 is a top plan of a paint mixer embodying the various features of my invention. Fig. 2 is a vertical sectional view of the same mixer taken on line 22, Fig. 1. Fig. 3 is a detail sectional view through the upper portion of the driving means for a mixer taken on line 33, Fig. 1. Fig. l is a top plan of the lifting blade on the lower end of the agitating arms, the latter being shown in section. Fig. 5 is a detail sectional view through the same bar taken on line 55, Fig. 4.

In order that my invention may be clearly understood, I have shown a paint pail or receptacle 1 open at the top and provided with a bail 2- hinged to diametrically opposite ears or lugs 3 so as to be capable of swinging in either direction from a vertical position.

The mixer preferably comprises a bar 1-- of slightly greater length than the diam'eter of the pail and supported diametrically upon the rim thereof as shown more clearly in Fig. 1, a portion of said bar be- Specification of Letters Patent.

ing of just sufiicient length to slide radially between the lugs -3 while other portions of the ends of said bar are provided with radially projecting lugs '5 for engaging one edge of said lugs and thereby limiting the sliding movement toward the opposite edge across the rim of the pail. This bar -4 is also provided with additional laterally projecting bars 6 and 6 of such length that their outer ends may rest upon the rim of the pail when the mlxer is adjusted for use, said outer ends being preferably united to each other while the inner ends are united to the bar 4l, thereby constituting a main supporting frame for the movable parts of the mixer.

The bar 4-- is provided near its junction with the lateral bar 6" with a vertical opening -7 which, in this instance, is coaxial with the axis of the pail 1 for receiving the hub 8-0f a bevel gear -9, thereby forming a bearing in which this bevel gear is rotatable, said gear and hub being also provided with a central opening in which is secured the upper ends of a pair of agitating rods 10 of rounding cross section extending to a point in proximity to the bottom of the pail for receiving and supporting a paint-lifting bar 11, the latter being preferably movable rotarily across and in close proximity to the bottom of the pail 1-- and is rigidly secured to the lower ends of the rods 10-.

The lifting bar 11 is preferably made of flat sheet metal having its ends twisted in opposite directions so as to incline downwardly and forwardly in the direction of rotation, thereby lifting the paint solids from the bottom of the tank where they are most liable to collect by reason of their heavier specific gravity and elevating such solids into the superposed oil where they are caught by the agitating rods 10 and given a circumferential whirling motion to thoroughly equally mix such solids with the oil, thus reducing the paint to the desired consistency for distribution over the surface to be painted by suitable brushes. In order that this agitation may effect a rapid and thorough mixing of the paints, the upper portions of the rods 10 are bowed downwardly from each other or rather from the axis while their lower ends are similarly deflected outwardly and secured to the ends of the bar 11 which is of approximately the same length as the interior diamet r of the pail, the lower outwardly bowed portions of the rods being of slightly greater radius than the upper outwardly bowed portions so as to more effectively remove the solids from the sides of the pail where they are disposed to accumulate more or less.

The means for driving or rotating the agitating rods -1.0- and plate or bar 1l consists of a driving shaft 12-- and a counter shaft 13, both of said shafts being located side by side in parallelism upon the main supporting frame along the bars 6* and 6 respectively. The driving shaft -12 is journaled in suitable bearings H- rising from the main supporting frame and is pro vided with spore gears -15- and 1(iof different diameters, the gear being somewhat smaller than the gear -1(3 but both of these gears are secured to the shaft l2 as shown more clearly in Fig. 3. This shaft may be driven by any suitable power and is shown as provided with a hand crank 17 by which it may be turned at any desired speed. The counter shaft -13 is also journaled in upstanding bearings 18 rising from the main supporting frame, as shown more clearly in Fi 2, and

is provided with a relatively large gear --l9- and a compa'atively small gear 20, both rigidly secured thereto and adapted to mesh respectively with the gears 15 and 16-. The gears -19 and 20 are spaced a sufficient distance apart axially to permit the gear 1'5 to be thrown out of mesh with its companion gear l9 by axial movement of the driving shaft 12* sufficient distance to bring the gear 1tiinto mesh with the smaller gear -20, thereby dr' ing the counter shaft 13 and mixer with greater speed than when the gears 15 and 19 are in mesh. As previously intimated, the driving shaft 12 is movable axially in its bearings -14 to shift the gears for varying speeds in the manner just previously described.

hen the main supporting frame is mounted upon the rim of the pail in the manner previously mentioned so that the extensions bear against the adjacent edges of the lugs or ears 3- on the pail, the bail 2-- is rocked downwardly into engagement with an upstanding arm 21 5o rising from the main supporting frame, as shown in Fig. 2, the upper end of the arm being n'eferahly notched to receive and support the bail against further downward movement so that a part of the arm extends downwardly at the inside of the baih thereby holding the main frame from being withdrawn radially or outwardly in one direction while the engagement of the lugs 5- agzitinst the ca rs -3 prevent movement of the frame in the opposite direction, the eyes, as 22 of the bail which are engaged with the cars 3 being disposed in close proximity to the upper faces of the adjacent ends of the bar l to hold the frame against upward movement.

hat I claim is:

1. A paint mixer comprising a pail hav-- ing a bail, a frame resting on the upper end or rim of the pail and engaged by the ends of the bail, said frame being provided with an upstanding arm for interlocking engagement with the bail to hold the frame on the pail, a rotary mixer on. the frame, and means for driving the mixer.

A paint mixer comprising a receptacle having diametrically opposite apertured lugs and a bail hinged thereto, a frame slidable across and upon the rim of the receptacle and against one side of said lugs beneath the ends of the bail, means on the frame for interlocking engagement with the )ail to hold the frame against said lugs, rotary mixer supported by the frame and driving means for the mixer also supported by the frame.

In witness whereof I have hereunto set my hand this 31st day of May, 1913.
